Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the grinding machine uses a fixed rubber belt configuration, then the structure is simple, but it cannot adjust the tightness and angle making it difficult to grind larger objects
Solution Approach 1:
The patent applies the dynamics principle by making the rubber belt system adjustable rather than fixed. The belt tension is made dynamically adjustable through a tensioning mechanism that allows the belt to be tightened or loosened. The belt angle is made adjustable through an inclined plane mechanism that can be tilted to different angles. This transforms a static configuration into a dynamic one that can adapt to different grinding requirements.
Solution Approach 2:
The patent applies parameter changes by allowing modification of key parameters of the rubber belt system: the tension parameter can be changed to adjust tightness, and the angle parameter can be changed to adjust the inclination. These parameter changes enable the same belt system to handle objects of different sizes and shapes, improving versatility without requiring multiple different belt systems.
2Manufacturing precision
If the rubber belt is fixed in tension, then the structure is simple, but it cannot be adjusted for precise grinding of different objects
Solution Approach 1:
The patent applies segmentation by dividing the belt tensioning function into separate adjustable components. The tensioning mechanism is segmented from the main belt structure, allowing independent adjustment of belt tightness. This segmentation enables precise control of belt tension to achieve optimal grinding precision while maintaining ease of operation through modular adjustment.
Solution Approach 2:
The patent introduces intermediary mechanisms to facilitate adjustment: a tensioning device acts as an intermediary between the belt and the frame to control tightness, and an inclined plane structure acts as an intermediary to control the belt angle. These intermediaries make precise adjustment easier by providing mechanical advantage and controlled movement.
3Area of stationary object
If the grinding machine has a fixed work bench angle, then the structure is simple, but it cannot treat larger area of objects
Solution Approach 1:
The work bench is transformed from a static fixed-angle structure to a dynamic adjustable-angle structure. The inclined plane mechanism allows the work bench to be tilted to different angles, enabling the grinding surface to accommodate objects of various sizes and shapes, thereby increasing the effective grinding area.
Solution Approach 2:
The patent introduces angular dimensionality to the work bench by allowing rotation or tilting around a pivot point. This adds a rotational degree of freedom to the previously fixed structure, enabling the work surface to be oriented at different angles to match the dimensions and orientation of objects being ground.

AI summary
A grinding machine includes a support and a board which is connected to the connection portion of the support. The board has a first opening and a second opening. A transportation device is connected across over the first and second openings. A grinding device has a driving portion and a grinding portion which is connected to the driving portion. The driving portion is connected to the support so that the grinding portion is located above the transportation device. An angle adjustment device is connected between the board and the transportation device so as to adjust inclination of the transportation device so as to grind a larger area of an object.
